Merge tag 'cleanup-omap-tags-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup
From Tony Lindgren:
Remove the ancient omap specific atags that are no longer needed.
At some point we were planning to pass the bootloader information
with custom atags that did not work out too well.
There's no need for these any longer as the kernel has been booting
fine without them for quite some time. And Now we have device tree
support that can be used instead.
* tag 'cleanup-omap-tags-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP: remove plat/board.h file
ARM: OMAP: move debug_card_init() function
ARM: OMAP1: move lcd pdata out of arch/arm/*
ARM: OMAP1: move omap1_bl pdata out of arch/arm/*
ARM: OMAP: remove the omap custom tags
ARM: OMAP1: remove the crystal type tag parsing
ARM: OMAP: remove the sti console workaround
ARM: OMAP: omap3evm: cleanup revision bits
ARM: OMAP: cleanup struct omap_board_config_kernel
+ sync to 3.6-rc5
